I, LEWIS S. DANIELs, of Foxborougli, in the county y spective.

Figure 2 isa vertical section ofthe same. v Figure 3 is au end view,showing a. portion ofthe division-plate H' within the lower part A ofthe radi-- ator.

Figure 4 is'a cross-scction of one of the vertical pipes'. y

Figure 5 is a pex'spective;vie\'v of one of, the caps and its stem. I

General Desciptiom One of the leading features of my invention is thatthe uprights B B' are castas aV single piece with the horizontal part A,the number of thc' uprights B B' beingv varied to suit the amount ofheating-surface desired.

@Another feature is the shown in iig. 2.

This division-plate startsii'om the lower part of the lower pipe Aandextends upward nearly to the top of the vertical pipe, as shown infig. 2.

vertical division-plate H,

The upper ends of the division-plates are provided with bosses K K',into which. the stem of the caps I) and E screw. The cap D is beveled,asshown in iig. 2,'and is heid iu position by means of the stem L, whichscrews into the vsocket K. A

The cap E is rabbeted, as shown iu iig. 2, andv is held iu position .bymeans of the stem L', which screws into the socket K'. n

The caps C and C are screwed outo'theeuds of the lower radiator, asshowuzin figs. 1 aud 2.

The division-plates .H and Hf are. pelforated near the bottoni, as shownat p and p, figs, -2 audg, so as to allowl the water of condensation toflow through.

, The .connecting-pipe' for direct steam and. for return vmay be`attached by any of the improved methods.,

By my arrangement 'I' secure great economy of construction'l aswenas-simplicity and security against leakage.

Another', aud perhaps the .most important feature" of this invention, isthat I secure a most perfect circulation of steam over-andagainstthe'eutire 'sur face of the radiator, and without interfering iuthe least with the circulation of .the water of condensa? tion. I l Iclaim as my invention- 'A steam-radiator, consistingoi the tube A',up
